Focuses on the anatomy of the eye and the physiological processes involved in vision, including the retina, lens, and optic nerve. Useful for students preparing for anatomy or physiology exams.
Neurotransmitters can be either excitatory (e.g., glutamate) or inhibitory (e.g., GABA), depending on their function.

Dendrites receive signals from other neurons and transmit them to the cell body.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Sensory Organs - Eye - Structure and Physiology of Vision
Neurons are highly specialized cells that transmit electrical and chemical signals but have a limited ability to divide.

The parasympathetic nervous system is responsible for promoting digestion, slowing the heart rate, and relaxing the body.

Serotonin is involved in mood regulation, and its deficiency is often linked to depression.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Sensory Organs - Eye - Structure and Physiology of Vision
The parasympathetic nervous system promotes relaxation, lowers heart rate, and enhances digestion.

Hydra has a simple network of neurons called a nerve net, which lacks a central control system.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Sensory Organs - Eye - Structure and Physiology of Vision
Acetylcholine is the neurotransmitter that facilitates communication between neurons and muscles at the neuromuscular junction.

The autonomic nervous system regulates involuntary functions such as digestion, respiration, and heart rate.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Sensory Organs - Eye - Structure and Physiology of Vision
Interneurons act as a bridge between sensory and motor neurons, helping process and relay information.
